ully Boy took a good opening of around 40-45% overall while cities like Mumbai and Pune took a blockbuster opening which can compare with the biggest of films. The opening of this film was far bigger than Padmaavat and Simmba in Mumbai / Thane and Pune. This is probably due to the local feel of the film.
The film had a Thursday release because of Valentines Day. It is not an official holiday but collections do get a boost. The last two years have seen the release of films like Jolly LLB 2 and Pad Man and they got a boost of 25-30% despite not having much for the youth. Gully Boy should get a bigger boost as its a film for the youth with youth stars but it will be the collections tomorrow which will tell how much the boost was.
The film is econically safe as most of the cost to make it and release it will be recovered from digital, satellite and music but that is the case with most major films but the theatrical run is most important for the people involved to benefit.
